Package: dovecot-core
Version: 1:2.3.4.1-5+deb10u1
Severity: normal
Dovecot regards 'nobody' and 'systemd-coredump' as valid users.
root@rolly# doveadm user '*'
nobody
nick
systemd-coredump
In an attempt to remove them, I edited dovecot/conf.d/10-mail.conf to
set the range of user ids.
first_valid_uid = 1000
last_valid_uid = 1100
But dovecot was then unable to list users successfully.
root@rolly# doveadm reload
root@rolly# doveadm user '*'

Error: User listing returned failure
Fatal: user listing failed
